Danish police sent extra personnel and sniffer dogs to Greenland as the icy island steps up security measures ahead of a planned visit this week by Second Lady Usha Vance, the chief spokesman for Denmark's national police said.
René Gyldensten said Monday the extra officers, deployed the day before, were part of regular steps taken during visits by dignitaries to Greenland, a self-governing, mineral-rich territory of American ally Denmark.
